Neither one of you had a response to why is had taken over a year to find out about this mistake but you both agree that it is better to wait. Also for Poopy Head, the link in your post was for an article twenty four years old. Can’t you find anything more current? Oh well, checking the sun dial it is time to retire.
As you mentioned, Aldicarb is highly toxic and closely regulated. According to what I’ve read, its rate of decomposition is greatly affected by temperature, soil pH and the amount and type of sediment found in the aquifer or body of water. Those three things being near constant in this area, sure, the link went to old science, but I’d say the science is probably still good.
My experience with this sorta thing is with herbicides, especially those used in aquatic and invasive plant management. Similar, but different. Same basic principles, same type of precautions are used with each. From the University of Florida - Institute of Food and Agricultural Services (UF/IFAS), a link that lists the approved uses (citrus being one) and applicable restrictions, and includes information regarding drinking wells:

Why a year to discover the error? We may not learn that until the investigation is finished.
